9. CALCULATION EXAMPLES OF LVL STRUCTURES
The wall studs is installed on a 120 mm wide LVL 48P sole plate, which has compression perpendicular to the
grain flatwise strength fc,90,flat,k = 2,2 N/mm2. The resistance is
F_(c,90,d) = N_d = 22,3 kN
σ_(c,90,d)=F_(c,90,d)/A_ef =(22,3 kN)/(b∙(l_support+2∙30 m
σ_(c,90,d)=1,77 N/mm^2
k_(c,90)∙f_(c,90,flat,d)=k_(c,90)∙k_mod/γ_M ∙f_(c,90,flat,k)
k_(c,90)∙f_(c,90,flat,d)=1,4∙0,8/1,2∙2,2 N/mm^2 =2,05 N/mm^2
(kc,90 from Table 4.7)

0,45 ∙ 17,3 Nmm2 + 0,7 ∙ 6,2 Nmm2
20,7 Nm 2 = 0,52 + 0,7 ∙ 0,30 = 0,73 → OK
c,90,d = d = 22,3 kN

c,90,d = 1,77 N/mm2
c,90 ∙ c,90,flat,d = c,90 ∙ mod M∙ c,90,flat,k
c,90 ∙ c,90,flat,d = 1,4 ∙ 0,8 1,2∙ 2,2 Nmm2 = 2,05 N/mm2 (k c,90 from Table 4.7)
c,90,d ≤ c,90 ∙ m,0,flat,d → OK
